No-hub pipe must be no more than 25/1000 below mfg. nominal OD, to assure water-tightness
– If no-hub pipe isn’t ideally smooth & properly sized, caulk may be needed for water seal

Insert the pipe up through sleeve from below, providing the best chance for water-tightness
– Keeping the pipe in the center of the sleeve will provide the best water-tight results– For especially tight pipe fits, apply soapy water solution prior to pushing pipe through

If desired, for added strength, use ½” long #8 screw to attach Locator Whiskers to safety cap

If desired, for added strength, use ½” long #8 screw to attach outer sleeve to inner sleeve
